Learn how to visualize the correlation between technology products purchased, using a visually appealing Correlation Matrix. The correlation matrix is great for visualizing similarities between items in your dataset. In this episode, we will be calculating the Pearson Correlation Coefficient through the Tableau CORR() function while using Level of Detail calculations. - วิทยาศาสตร์และเทคโนโลยี

Thanks for video . It was a respite for me after persistent struggle for creating correlation heat map with unstacked data set
Great job! Can correlation analysis be used to display the correlation between likert questions?
Fantastic, well explained. Thank you , I really enjoyed listening to your presentation.
I can't understand which formula you use in the Pearson correlation coefficient, please can you tell me that formula.
very well explained! thanks!!
Lekker tutorial man! So clear and concise!
Hi, I'm needed to use this in my assignment, but because I'm needed to take a snipshot of the correlation matrix and paste it into a word document, I'm not quite sure how I will be able to 'hover' above each grid to show the numbers.
Hence, I wonder if it is possible to replace the color dot/grids with the colored numbering of the correlation value.
omg this is awesome and so simple, thank you SOOOO MUCH!!! helped me a lot!
Hi, could you plz help in analyze CORRELATION MATRIX???
U r doing great job .Thanks a lot
what if when i put filter of brand field so brand filter will filter the visualization for both row shelf brand field & column shelf brand field.
I want if brand slect only apple and dell then correlation show between these two value only but i am unable to do that because its filtering only one filed not both the field , as we have taken brand filter from one data source only.how to merge brand filter from both the data source
?
Hello, Dear Teacher, I want to make this correlation matrix chart, I do try my best but I can't make it,
When I place mark in columns and mark1 in rows, some blank cells appear. When I put the calculated correlation coefficient, some cells appear empty and others filled but without number.
I do not know what is the problem
Clear and well articulated!
I have a question: would there be any difference if you used fixed instead in this particular example?
Hi Nirvan, in this particular example you could also have used the FIXED keyword in stead of INCLUDE, and achieving the same results.
Very helpful tutorial ... explanation was crisp clear.
You are most welcome Anil!
Thanks for this tutorial. But I am wondering how to create a correlation matrix for all the measure variables
Hi Siva, with some additional work and through use of parameters you can easily adapt the correlation matrix to work across all dimensions. Have a look at this great example from Kevin Cain on Tableau Public: public.tableau.com/profile/kevin.cain#!/vizhome/CorrelationMatrixexample/CorrelationMatrix
any idea what the problem could be if i only get a single diagonal line with a pearson correlation coefficient of 1? my columns and rows are item_number to item_number1 and the formula i'm using is: CORR({INCLUDE [custom_id]: sum([Quantity])},{INCLUDE [custom_id1]: sum([Quantity1])}) .
b_rizzle tom cizeron hi were you able to get ABC values all over instead of only diagonal?
beautiful!
Thanks!
Hi ! I try to do the same thing but when I add my two "Brand" (like at 3min in the video) I have only value in the diagonale, so when I add my correlation to the color I have only values 1 in the diagonale, I don't know how I can solve this problem... Can you help me ?
tom cizeron hi were you able to get ABC values all over instead of only diagonal?
I have same problem
this seems to not work in 2021
So much more intuitive than ANOVA's...
Indeed :)
Is it just me or CORR() as well as COVAR() does not exist anymore in the latest Tableau version??
its under Aggregate in formula categories
